Problems solved by technology

This method has the characteristics of simple matching and strong anti-interference ability, but it also has certain shortcomings. For example, in the case of supporting Chinese characters and many fonts, the amount of data that needs to be stored and matched will greatly increase.

Embodiment Construction

[0045] In the statistical pattern recognition method, the Chinese character feature is based on the n-dimensional vector X=[x 1 , x 2 ,...,x n ], the dictionary contains n-dimensional feature vectors of each type of Chinese character. Recognizing a certain Chinese character is to use the distance and / or similarity formula to determine which n-dimensional feature vector of the Chinese character is closest to the n-dimensional feature vector of the standard Chinese character in the dictionary. Distance metrics usually include Euclidean distance, urban block distance, and Mahalanobis distance. Commonly used distance and similarity formulas are shown in formulas (1) and (2) respectively:

[0046] D ( X , G ) = Σ i = 1 n [ X ...

Abstract

A character identification method being optimized by template includes using at least one training character in training character set to structure a font, placing said font in different cluster set to pick up public templates of said font then storing picked up templates in template storing module, storing internal code of each font to be corresponded to pointer of various font public template to form font index table by template output unit, carrying out level by level matching of character to be identified with various public templates pointed by a found font index table then recording matched result for obtaining candidate character.

Description

technical field [0001] The invention relates to a character recognition method and system, in particular to a template-optimized statistical pattern recognition method and a system for executing the method. Background technique [0002] The research work of Chinese character recognition technology in our country started in the early 1980s, and its development has mainly gone through two stages. The first stage was the entire 1980s, and the main research in this stage was the exploration of various algorithms and recognition schemes for Chinese character recognition. The second stage began in the 1990s. Chinese character OCR technology entered an important and vigorous development period. The research results of the laboratory were pushed to the market, and many new algorithms and technologies for Chinese character recognition appeared. [0003] At present, printed Chinese character recognition technology is very mature, and there are many kinds of algorithms, but they basic...
